[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a rotary switch, such as Figures 1-4 As shown, the device includes a knob housing 1, a touch panel 2 mounted on the top of the knob housing 1, a cover plate 4 at the bottom of the touch panel 2, and a circuit board 3 mounted at the bottom of the cover plate 4. A battery compartment 5 is installed in the center of the knob housing 1, containing a battery 6. Several touch switches are mounted on the top of the circuit board 3. Pressing the touch panel 2 activates the touch switches on the circuit board 3. A main frame 11 is mounted on the inner wall of the knob housing 1, and the knob housing 1 rotates in conjunction with the main frame 11. Through a unique design concept, a perfect combination of knob operation and touch operation is achieved. Specifically, by mounting the touch panel 2 on the top of the knob housing 1 and placing the circuit board 3 on the cover plate 4 below it, the user can easily operate the touch switches on the circuit board 3 by simply pressing the touch panel 2, thereby easily controlling the on / off state of the switch or switching between different functions.

[0024] Meanwhile, the battery compartment 5 and battery 6 located in the middle of the knob housing 1 provide stable power support for the switch, enabling the knob switch to work normally without an external power source, greatly improving its practicality and portability. The rotational fit design between the knob housing 1 and the main frame 11 ensures that users can experience a smooth and stable operation when rotating the knob.

[0025] In this embodiment, a battery compartment cover 14 is installed at the bottom of the battery compartment 5. By installing the battery compartment cover 14 at the bottom of the battery compartment 5, the battery 6 is effectively protected from damage caused by external impact or vibration. It also prevents dust, moisture and other impurities from entering the battery compartment, extending the battery's service life and ensuring the stable operation of the rotary switch.

[0026] Specifically, several magnets 13 are installed at the bottom of the knob housing 1. This allows the knob switch to be easily attached to metal surfaces, such as refrigerators and metal walls, saving installation space and improving installation flexibility and convenience, thus meeting the user's needs in different scenarios.

[0027] Furthermore, several locking bolts 12 are installed on the main frame 11, with the ends of the locking bolts 12 penetrating the circuit board 3 and being connected and fixed to the cover plate 4. This design enhances the structural strength of the rotary switch, ensures a tight connection between the components, and improves the stability and durability of the switch, maintaining good performance even after prolonged use or exposure to external impacts.

[0028] Furthermore, a base 7 is installed at the bottom of the knob housing 1, and the bottom of the main frame 11 is connected and fixed to the base 7 by bolts. This provides a stable support for the knob switch, preventing the switch from shaking or tilting during use, and further improving the stability of the switch and the user experience.

[0029] Furthermore, several contact switches are mounted on the outer side of circuit board 3. The knob housing 1 rotates and contacts different contact switches, achieving the knob switch effect. This allows the knob housing 1 to contact different contact switches during rotation, thus realizing the multi-functional switching effect of the knob switch. This design not only enriches the switch's functionality but also improves operational flexibility and convenience.

[0030] Furthermore, the inner wall of the knob housing 1 is fitted with ring teeth, and the outer wall of the main frame 11 is fitted with locking blocks that engage with the ring teeth. This ensures the stability and accuracy of the knob housing during rotation. This design prevents the knob housing from slipping or wobbling during rotation, improving the rotational accuracy of the switch and the user experience.

[0031] Furthermore, the size of the touchpad 2 is adapted to the size of the cover plate 4, and the touchpad 2 is glued and fixed to the top of the cover plate 4. This design not only simplifies the assembly process of the switch, but also improves the stability and responsiveness of the touchpad 2. Users can experience a smoother and more comfortable touch experience when pressing the touchpad.

[0032] When the user lightly touches the touch plate 2 on the top of the knob housing 1, the touch plate 2 is pressed and deformed. This deformation is transmitted to the circuit board 3 below the cover plate 4. The circuit board 3 is equipped with several touch switches. When these touch switches are pressed by the touch plate 2, they trigger corresponding circuit changes, thereby turning the switch on or off or switching between different functions. After the touch operation is completed, the touch plate 2 returns to its original shape due to its elasticity, waiting for the next touch.

[0033] Users can rotate the knob housing 1. The knob housing 1 and the main frame 11 are designed with a rotating fit, ensuring smooth and stable rotation. During the rotation of the knob housing 1, the annular teeth installed on its inner wall cooperate with the locking blocks on the outer wall of the main frame 11, ensuring the accuracy and stability of the rotation and preventing slippage or shaking. Several contact switches are installed on the outer side of the circuit board 3. When the knob housing 1 is rotated to different positions, it will contact different contact switches, thereby triggering corresponding circuit changes and realizing the multi-functional switching effect of the knob switch.

[0034] The rotary switch has a battery compartment 5 inside, which houses a battery 6, providing stable power to the switch. A battery compartment cover 14 is installed at the bottom of the battery compartment 5, effectively protecting the battery 6 from damage due to external impacts or vibrations, and also preventing dust, moisture, and other impurities from entering the battery compartment, thus extending the battery's lifespan.

[0035] Several locking bolts 12 are installed on the main frame 11. The ends of the locking bolts 12 pass through the circuit board 3 and are connected and fixed to the cover plate 4, which enhances the structural strength of the rotary switch and ensures a tight connection between the components. A base 7 is installed at the bottom of the knob housing 1. The bottom of the main frame 11 is connected and fixed to the base 7 by bolts, providing a stable support for the rotary switch and preventing the switch from shaking or tilting during use. Several magnets 13 are also installed at the bottom of the knob housing 1, which allows the rotary switch to be easily attached to metal surfaces, such as refrigerators and metal walls, improving the flexibility and convenience of installation.

[0036] Finally, it should be noted that the electronic components in the circuit board 3 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order of each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
